The main components of salmon are water, protein and fatty acids. There is little change in quality between cold storage and freezing, which can prolong the shelf life of salmon and increase the storage time. So salmon can be refrigerated or frozen, but in different ways and at different times.

2 How to put salmon in cold storage 1? Use kitchen paper to remove the oil from the surface of salmon.

2. Then wrap the salmon in a fresh-keeping bag and put it in a fresh-keeping box.

How long can salmon be kept at room temperature? If salmon is stored at room temperature, it is best to eat it within 2 hours. Because bacteria are easy to breed at room temperature, oxidizable components will be oxidized, so it can be stored for up to 2 hours.

Frozen salmon can be stored in the cold storage for 2 to 4 days, because the temperature in the cold storage is relatively low and bacteria are not suitable for breeding, so it can be stored for 2 to 4 days.

Frozen salmon can be kept for about 20 days, because bacteria are difficult to reproduce in freezing, and it is not a problem to keep it for about 20 days.
